Detailed explanation-1: -The eyepiece, also called the ocular lens, is a low power lens. The objective lenses of compound microscopes are parfocal. You do not need to refocus (except for fine adjustment) when switching to a higher power if the object is in focus on a lower power. The field of view is widest on the lowest power objective.
Detailed explanation-2: -An eyepiece is a magnifier with its entrance pupil defined by the lens stop of an objective lens. It is also known as an ocular lens. A typical ocular has a focal length of 25 mm, which is one-tenth of the near point of human vision at 250 mm. An image conjugate of the tube lens serves as the object of an ocular.
Detailed explanation-3: -Microscopes use convex lenses in order to focus light.
Detailed explanation-4: -Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above).
Detailed explanation-5: -Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available, typically from 5x-30x. Eyepiece Tube holds the eyepieces in place above the objective lens.
